My local garage said that they'll do 4 wheel alignment on my MY99 for £20, using a lazer.

It's only £20 and they can't mess things up that much can they?

Also, what figures should I give them?

£15 quid near me.

How come 4 wheel laser alignment is so cheap??

I've had 4 wheel Computer alignment (Using a Hunter computer thingy)and that cost me £60-70 plus the VAT.

Took a good 45 mins or more and they provide you with a colour copy of the 'settings' before adjustment and after.
All in a nice little wallet.

Is laser just as good??

What's the pros and cons of using either??

Local place to here used to be free check but 25 quid if things needed adjusting... and you got a before & after printout :)

Laser setup is not a geometry setup, thats why its cheap.

Laser is basic it just sets the front and rear wheels to run perfect to each other, where as a full geometry setup does the entire handling package, so to speak.
