I was recently turned on to a really great German car mechanic in southern CT. who straightened out some emissions problems on my M3 that had me stumped for about a year...not a stdealer. This guy has 45 years of german car experience and does not advertize...word of mouth only. If interested, his name is Deiter and he runs North Haven Foreign Car Repair on Washington Ave in North Haven, Ct. If you need an honest and capable mechanic in southern New England, call Deiter @ 203 239 3247
