Coming from old Japanese cars before buying my z4 coupe, I am accustomed to not even looking at mileage and just going on condition and what you can find/evaluate from history and owner.
I remember buying a mk1 mx5 without even asking the mileage before viewing and not even checking when visiting. Just looked for the usual rust and normal things for looking at when buying a car, Turns out it was 200,000+km, I added about 6-7000 miles to it and then sold it, the guy i bought it from bought it back.
In fact it was my lowest mileage car i owned, an e46 318 which caused the biggest bill when its decided it didnt like its head gasket on the m74 and left me stranded for 4 hours. Cost an expensive emergency sign up to AA to get home and £500 for head skim and gasket.
All other cars, civic vti's, integra type R's, toyota celica have normally been 100,000+ miles and no big issues.
Theres a common theme than most remedial work is going to be required around 70,000 miles, shocks, bushes, clutches etc but these can go anytime really and you cant predict it but at the age of z4's now regardless of mileage things are going to need to be replaced every now and then, even if you buy your bumped up price for "low mileage"
I really dont understand the price with all z4 variants in regards to mileage, people put huge disparity on prices on mileage which ive never understood, seeing 3k price differences over near identical spec because of a 40,000 mile difference. I would take the money saved and put into fuel for driving the thing or some dampers, springs, bushes and pocket the rest. And even that 50,000 mile car which is now going to me anywhere upto 12 years old may need the same things, but you have already paid the higher price.
Il just have to take the hit when my coupe nudges into 6 figures. Thing i bought mine on around 92,000ish, so far its needed a brake caliper when one was sticking. an exhaust hanger bracket which snapped off and i think thats been it. no other problems in 2 years for those "high mileage cars"
