Hello and welcome!
Nice looking previous cars you had there. Rims suit the Volvo quite well.
There are a few members on here that are upward of 100,000km and without too many issues, hopefully some can comment here. Generally the reliability is pretty good, however some have had turbo seal issues or in my case water pump leaking seals. Other than that they're pretty much go hard cars really. Btw the CAI is gonna sound sweet! Just a word of advice, you may have to modify the mounting plate to miss the refrig pipework (the intake was designed for LHD US vehicles)
