Whats the difference? (Alignment shop)

[unklekraker]

Last week I started looking for a alignment shop for my Boxster's 4 wheeels and was recommended by 2 people to the one, about 15 miles from where i live and it will cost me $250 plus i have to leave the car there for a day for them to align it, check suspension, steering, brakes and what ever needs to get it fix but limited to major repair.. Then there's Sears, about 3 miles and their price is $95 and will take them 1.5 hours to align it, check suspension, steering, brakes and what ever needs to get it fix but limited to major repair and then there's Goodyear shop, about 10 miles and the cost of the same service is $135.

SO the question is, why big differences on price with the same service? would you trust Sears?


Thanks in Advance....
