SMG / CSL parts bin are a plus for me. The red interior seems to be a common UK thing . It’s going to be more collectable than standard models.
Biggest expense on these is worthy tyres in my experience.. People worry about bearings / smg pumps , subframes , vanos , biff bolts , cam bolts , steering hoses , coil packs , gear position servos , head gasket , alternator replacements etc. With mine it’s done 160,000 and I’ve driven 115,000 of them.over past 7 years.
biggest expenses... $9k on rubber. Or $25k on gas. , $21k on parking , and $1200 per year in dealer serving and parts. I think some times we focus on the maintenance costs on e46 M3s where as the costs are elsewhere. $30k for the cs seems like good value for a car that is a joy to drive.
