Volvo Repair: Wheel Alignment, wheel alignment, 30 minutes

Question
Hi,
I have Volov 850(1995) and need to have wheel alignment done for it.  I checked and found out:
1) 30 minutes, $60.00
2) 1 hour, $45.00
3) 2 hours, $80 (dealership)
I need to know how long should it take.  The 1 hour guy tells me that Volvo alignment takes longer because it is harder.  If you could possibly tell me how long it should take and what signs I should check once it is done, it will be great. I thank you in advance.  Regards, Jafar  

Answer
HOW LONG IT TAKES DOES NOT MEAN THAT IS HOW MUCH THEY CHARGE.THERE SHOULD BE A FLTE RATE WHICH UNDER WARRANTY IT IS ABOUT 1.5 HOURS LABOR FOR A 4 WHEEL ALIGNMENT. MOST PLACES USUALLY JUST CHARGE A SET RATE.IT SHOULD TAKE ABOUT 30 MINUTES TO DO BUT IT MAY STILL COST 80 DOLLARS.
