Although all of my cars have served me more or less well, I don't want any of them back.
I bought my first car at the age of 32 or so, an Audi 100 from '82 with some half a million kilometres behind it. Had it for a couple of years, sold it with 620k in the meter. Then went to old MB's, a W124 sedan followed by a five years younger wagon and after crashing it bought a W210 facelift which got a gear box failure after a few years after which I got this current W210.
When I got my license at the age of 18 my dad had the intention of getting me an old banger to learn the basics, instead he bought a house and let me drive his Fiat 127 whenever he was abroad which happened often enough. Later I got a job as a sales rep and the company gave me a new car to drive every couple of years. Starting with a Nissan Cherry, followed by a Toyota Carina II, a Peugeot 205, a VW Golf II, a Jetta II and a Vento.
Don't miss any of them.
