Sorry - I do all my own work partly because I haven't found anybody myself.
I ended up with a V8 XC90 - crazy cheap because it was misfiring on 3 cylinders and had a grinding angle drive. Previous owner was sick of pouring money in. The local "mechanic" had resealed the valve covers (ie no new gaskets just heaps of silicone) and broken 3 earth connections for the ignition coils. The angle gear had been replaced when the transmission was rebuilt just before I bought it - the original came with the car and has been perfect for 120,000km.
My wife has an S40 T5 AWD - picked up from a friend with a blown engine (not in the good sense...) He had a local garage replace the timing belt due to age only, and the mechanic also installed a cheap Chinesium water pump "whilst he was in there". Water pump failed after 25,000km and of course there's a washer bottle level sensor but not a coolant level. Grrrrr...then again, if the gorilla had left the original pump alone we wouldn't have it !
I've become a bit of a fan for the 2000 - 2010 Volvo models, but I'm not a mechanic so I can't help you there. The cars aren't actually that complicated, but most mechanics have done more harm than good from my experience. More than happy to help out with suggestions - this forum has helped me more than once and there are plenty of people here who have been there and done that.
I'd suggest if you need parts, don't use the local dealers unless they have a defibrillator in the spare parts office. Genuine Volvo parts much cheaper if you order from FCP, IPD, Volvopartswebstore etc in USA. Typically only a week for delivery and much cheaper including shipping. Picknpayless (Blacktown Sydney) have also been doing a run on Volvos - they crushed 3 of your model in the last few months but none there just now.
