I also vote yes to keeping your Coupe
Considering I am President of this Club, my Coupes have always been in just about roadworthy condition and always ran on a shoestring budget, which isn't great considering it's my every day car
I will be losing £336 in wages/income a month from July from my second job as I'm being made redundant, but I haven't even considered getting rid of my Coupe. You're not out of the income bracket of running a Coupe, it doesn't cost any more than running any other car. I know this differs a bit for you as the Coupe isn't your only/every day car.
My beloved old Coupe kept me on the road for 10 years before the costs of repairs became too much and too extensive and had to come off the road. Rob40 on here was my saviour and bought me another Coupe. I have paid him back for it, but it was bought by him with unconditional love and terms and very much appreciated by me
I can do a lot of work on the Coupe myself, so that saves me money, but things like your tracking and a rocker cover gasket aren't expensive
I really wouldn't worry about the laquer peel on your Coupe. It's only cosmetic and doesn't 'need' to be fixed to keep driving it. My old Coupe suffered badly from this and the current one is the same and although they look a mess close up, I don't care as long as it's still road worthy.
Mine is nowhere near as nice as it should be, nor show quality like a lot of peoples on here are, but as long as I can drive it ever day, I'm not that bothered
You wouldn't get too many issues from your Coupe being parked up on your lawn for a few months. Tyres might get some flat spots, battery might die, but other than that, it'll probably be fine.
Your main issue at the moment is getting the fuel leak sorted. It could be something as simple as a leaking fuel filter, which just needs replacing or tightening up
I still have my old Coupe sitting on my drive Annie. I've only sold on the more desirable parts, such as some of the bodykit, etc., but if there's anything you needed that would fit your Coupe (mine's a turbo, but a lot of parts would still fit yours), I would be happy to send them to you for free if it means you can keep your Coupe
