I just spent $7,000 on my T5 2.5 TDI at ~25,000 miles, but the head's cracked (known fault) it needs a drive shaft (known fault) and while the engine is out, may as well do the clutch and DMF. That adds up to at least $15k at independent rates or about $24,000 at the dealer
Volkswagen? or Millionairewagen?
My mechanic says they all have issues from the Polo all the way up, they're designed to make it through warranty and then become a nice little(?) income earner for the spares and maintenance departments.
I've test driven everything else on the market and nothing comes close to my amazing 2.5TDI (including the new BiTurbo), I actually don't mind spending a bit of money maintaining it, but I have my limits.
