Re: Non Alfa specialist, can u trust em??? or pay the indie??
For the sake of 100ish pounds (which is the delta betweeen your mates price and a garage) i'd get an indie to do it.
My dad knows an Alfa mechanic, he can do cambelts for a cheap price, however I'd much rather pay the extra and have the peace of mind in case the sh*t hits the fan. IMO oil changes are a different thing and I'd be happy for a mate or dads mechanic to do an oil change for example or another smaller routine task...
End of the day, you pays your money, you take your choice!!
