0-100k sounds good somewhere here someone did time trials and 19 secs to 20 is good.
pretty sure the CR love being driven like they're stolen. Ask to speak to who ever worked on your patrol
and find out how he/she checked your hoses. Vacuum hose is 20c a metre just replace the lot yourself.
find yourself a good diesel mechanic ,one who'll keep your history, someone here may know someone for you
