To date, the only problems have been a sicking door lock, which resulted in the manufacturers immobilizer cutting in. Easily fixed with a drop of WD40!
Front wheel alignment slightly out causing uneven tyre wear.
This is the second GLSi I've owned, the first being stolen in 1998.
Seriously underestimated car, very quick although it would benefit from a higher ratio between first and second gears.
Not too expensive to run, but can be a little thirsty if driven hard.
Unfortunatley its starting to look dated now, although used market has plenty of excellent condition examples very cheap.
I've owned my 1991 GLSI for almost six years now, and I have to say that it is definitely a lot of bang for the buck. If Ford still made them (a little more rust resistant, longer 2nd and 3rd gears and ABS added) then they'd sell like hot cakes. They're actually very quick, faster to 60 by about 0.1 of a second or something than the RS Turbo, and I beat one flat out, albeit at the cost of a new head due to a tiny retainer pin coming out of the cog that holds the timing chain - a one in a million accident. Mine's a little dated now, and for a laugh I added a 4" back box, induction kit, ecotek valve and FSE valve and I tell you she don't half fly! A great car, very underestimated and bags of fun if you know how to drive it and treat it gently when in the rain and run it hard in the dry. Let's be honest, it's still quite a sexy shape in an odd way, and what the heck did the Mondeo do for image?
