I know what you mean, Ive had my E55k Estate for about 6 months now, its really only in the last month or so that ive really started to bond with it.
For some reason I had more LOVE for my old 210 E55 Estate even though the newer car is better in nearly everyway, I think part of my experience with the older car i bought was it almost needing rescuing, it wasnt bad but it needed wheels refurbing, some rust sorting, some minor mechanical bits doing and I really enjoyed that part of the process. We had been through that together!
The Black E55k Estate was/is in near perfect condition inside and out, she didnt need me as much lol. Ive been cycling to work this past few months and only use the car a couple of times a week but when I do it now really does feel very special and ive really started to love it.
Ive always changed my cars quite regularly, its almost like I love cars with flaws more which the E55k Estate doesnt have many - which is pretty dam stupid!!!
