Hi
Depending which state it came from depends how much less power it'll be making.
Being a left hooker, means the brakes should be loads better than the UK models.
Rear arches rust out, near the top, where the strut mounts, inner rear archs, bottom of the front wings, floor pan behind front seats, bottoms of the doors, if the drain holes get blocked, windscreen frame rots. All the usual places for a 21year old car. Biggest problem is the fuel filler neck, rots, falls into tank, gets sucked into the fuel delivery system and does something similar to 'sucking' it in the process.
If it's clean, do it, why not have something different for summer?
