i was initially going to trade my e92 325i in with them, the px price wasnt good, i managed to sell it to a local garage for £500 more, that was still £1000 short of what i thought was a reasonable price, but I knew the new car was exactly what i wanted and at a good price anyway and didnt want to miss it.
Its taken me years to accept the money you loose on cars, I used to always buy a car and make money on it (in the old days), now I just view it as the cost of enjoying something, same as the cost of going on holiday or eating out or what we spend on beer and wine
