Re: Reliable Alfa garage
i am in your area and there are 2 places i have used, SGT in Taplow, a bit of a trek its past Slough, they are the easiest dealer to reach but usual dealer rates apply, but they are pretty good.
the place I'd suggest you give a go are Thorobred in Laleham Staines, google them and give them a call. I have used them once and will be going back for my next service, although it sounds a little pricey for a minor service, both places have quoted me £200 just for oil and all filters.
HR Owen in chelsea is the closest to us but being in london I wasnt interested in paying their rates, they sell/service lamborghinis and bentleys i think, but i didnt trust the mechanics i spoke to on phone! their service shop is closer to us than chelsea but like i said, i've not been.
*noise could be anything, my heatshield is cracked and vibrates/rattles at low revs, getting that changed too.
