CAR park attendants usually only get the chance to look at £100,000 automobiles, not own them.

But John McGlynn isn't an ordinary car park attendant.

The 35-year-old describes himself as "the world's best qualified parking attendant".

Not because he knows the exact dimensions of a bay, or knows what material the white lines are made from.

But because he is the holder of a law degree, an accountancy degree and, thanks to car parks, keeps his motors - including an Aston Martin soft top, a Bentley and a Range Rover - in an underground car park at his city centre bachelor pad.

And it all began with a summer job looking after other people's cars.

"To be honest, it started out as a laugh - something I wanted to prove I could do - but the idea just grew from there," says John.

"I worked part time in a car park at university and decided to launch the business while I was a student at Strathclyde University."

Starting with a £10,000 bank loan as a 21-year-old and leasing a space near the airport in 1994, his business, Airlink, almost literally took off.

He is now worth some £10m, owns enough land at Glasgow Airport to house 4000 cars at his Park Safe site, employs 70 people and flies across the world as he takes care of the 18 companies that operate under the Airlink banner.

The commercial property arm of the business alone owns one million square feet of warehouses.

And while it's clear John delights in telling tales of travelling to Beijing at an hour's notice, or vowing to try to take a weekend off each month to visit another country like Sweden, it is the stories from life on the job that really gets him animated.

For the job has brought him close to the rich and the famous - even when he hasn't been too sure who they are.

"I remember when I was only a few months into the business and was filling in for one of my staff," says John.

"A customer - a certain Mr Dalglish - came up to the office looking for his car keys.

"We always ask for identification but he said his wife had his passport. I asked for another form of ID and he produced his Blackburn manager's pass.

"It was then the penny dropped and I realised who Mr Dalglish was. He was very nice about it and had a laugh as I was probably the only person in Glasgow who didn't recognise Kenny Dalglish."

But John had no idea one of the men he employed in the early days, John Smeaton, would go on to earn world-wide fame after the attack on Glasgow Airport.

The boy from Paisley - he studied at Paisley Grammar School and St Columba's in Kilmacolm - also has a few numbers in his phone. One famous name he can definitely recognise is David Tennant.

He is a friend of the Dr Who star since they met at a charity bash.

"I paid £5000 for David's Dr Who script from episode one, New Earth, which was being sold to raise money for Paisley Accord Hospice," says John.

"It's got his personal notes on it and is signed by him and Billie Piper - it's a piece of history about a Paisley boy done good. It will go to Paisley Museum when it re-opens after its refurbishment.

"I've offered David a free space anytime he wants at one of my car parks but I hope he doesn't turn up this weekend. Even Dr Who can't squeeze his TARDIS in - there's no room left!"

Thanks to the Glasgow Fair, the car park at Glasgow Airport is currently very lucrative, with almost every one of its 4000 spaces taken.

And while he won't be drawn on his wealth, he is clearly driven by financial targets.

He made a vow to himself he would own a Porsche by the time he was 25.

And chatting away, it is clear his wealth has continued to increase - as well as his love of cars.

"I set myself the target of owning a Porsche by the time I was 25," he says. "Four days before my 25th birthday I took delivery of a Porsche, but I couldn't drive it until I was 25 because the insurance hadn't been approved."

He adds: "I spent three years on a waiting list to buy an Aston Martin but it was a big disappointment when I got it - it didn't drive well and was too rattly.

"I have an Aston Martin soft top and a Bentley Arnage T.

"But I prefer to drive my Range Rover which is very functional and gets the job done."

John, who admires Scots tycoons Brian Souter and Jim McColl, had to battle back from the personal tragedy of his dad dying in 2005.

Still single, his friends and family have described him as one of Scotland's most eligible bachelors. And while the flash pad on George Square might point towards some super bachelor status, he is quite modest when it comes to being described as a great catch.

"I wouldn't describe myself as that - I'm far too modest," he says. "I like to wind people up when I go to posh functions. When I'm asked what I do I say, I park cars for a living'. They don't know where to look and when they see I've driven to the function in a Bentley I add, I've parked a lot of cars'."

But what does he feel when he sees other people parking their cars to head off on holiday when he is working 70-hour weeks?

"I don't do proper holidays as each trip I take has a purpose but I do go to Sweden and Estonia quite often. Also New York and Hong Kong. I am abroad every month," he says.

"But I might have a stab at a proper holiday and perhaps do a backpacking-style holiday in Australia. I missed out on all the student travel stuff as I was planning a business launch. I'd love to give it a go."
