I must've bought mine just after yours SMIT, in March it'll be 10 years.
Not sure what I'm gonna do with it TBH, never have time to get near it and I think it's probably done about 300 miles in the last 5 years.
Just boutght a new house and move in 3 weeks so after about another 6 months I might actually get the car over and do something with it, but I'm not making any promises. It probably needs about £400 to get it up and through an MOT, but I'm happy pottering about detailing the M5 in my spare time, how times change.
