Hi there is 123000 miles on my z3 1.8 I have some service history is this considered high milage

Calculate 12000 miles for each year to get average milage

Calculate 12000 miles for each year to get average milage

Just under 9k a year. Perfectly fine

Thanks for that, but is this high milage can I expect things to give trouble or are these engines good for a lot more

Keep up with Servicing and use good quality fluids and she'll be fine for another 123k ;)

Thanks, that gives me some peace of mind

My V-reg Z3 2.0 has 12,000 (that's right, twelve thousand), so I guess it's ok then.
