NSR at 76k on 03 2.5, seem to have lasted longer than most but common fault neverless. Only became apparent during recent dealer MOT, would not have noticed otherwise! Fairly unforgiving ride what with 18"'s on run-flat tyres and all so not suprising coils give out eventually. Mate ditched his RF's and saved considerably on replacements, need a can of foamy stuff if you dont wanna be stranded at side of road mind. Prefer the security they offer personally.
