If anyone here thinks a 370Z is dear to run, try a Lancer Evolution, like my remapped 2009 MR FQ 360 1X.
Ferrari-style costs for servicing, tax, insurance, fuel.
4,500 mile intervals at £350 a time. Top road tax. 18 mpg generally and once I got NINE mpg in Germany, having some fun.
Tyres every other month. The 370Z is a pussycat, a cheap to run one by comparison!!
