Near Merrick, NY, Lon Island, Zip Code Hassel 11566

Going to check out a 99 540i/6 this Friday in Merrick, NY (Long Island), and would like to take it to a reputable and good place for a pre-purchase inspection. Tried calling the local BMW dealer there today, (Hassel Motors, Inc.), but I just missed their bussiness hours. So I will try tomorrow, even if they will have room for me on Friday or even Saturday.

Anyone here live near area code 11566, or near that area that can recommend a reputable shop, or dealer for detailed pre-purchase inspection in the next two days, it would be great and appreciated. Should I take it to a dealer or independent shop? I will be taking a train from Virginia..

thnxs in advance,
Francino
