In the mid-90s my family sold an E12 525 manual (carb) for RM12,000 (or was it RM20k, can't remember) - no. plate BBL 3142.
The car was bought new in the 80's from BMW Concessionaire, had a 4 speed manual gearbox, leather seats and was immaculately maintained. The buyer called up 6 months later to ask if we have other cars to sell.
And yeah, I learnt how to do reverse parking in that car too!
