Age as well as mileage need to be factored in. Rubber seals wear with use and get brittle over time. Some parts will still age even if mileage is low.
It is true we like pic's. In particular pic's of rust. If you can catch the right angle to see straight through a rust hole yer get bonus points. A dramatic shot of the moon preferred or just yer foot will do.
When adding up repair costs its best to consider how long it will repair the vehicle for, and what may be on the horizon needing to be done in a year or two also. The obvious result being it will cost more to repair than buying a reliable Freelander 1 or 2. If you can afford the repairs and they will give you another say 4 years of disco motoring then I personally would consider that to be on a par with paying to have yer legs broken. But its a way of splitting the cost over a number if years to see what yer gain from the investment.
As a seasoned Freelander owner I can appreciate the feeling of joy to own yer own vehicle and will have become quite fond of it. So I can understand the emotional tie to want to keep it and repair it. Could you convince yer husband to do some if the work and the garage does the big jobs? Offer to buy him some more tools?
All vehicles need wear and tear repairs as they age. Have you spent a lot on it already? If so you would lose that money if you scrap it now. Continue to gain from previous repairs if you keep. I assume yer only do a low mileage so that reduces mechanical repairs as it will have less use and not be so eggspensive to maintain as other disco's in the future.
If yer struggling then get an mot done as suggested above by others. Its don't have to be official and registered. It's a cheap way if knowing what needs done now and what could be on the horizon. Knowing this will help advise the cost now and potentially in say 2 years time.
I had the same agonising problem with my Freelander 1. I'd spent over 7,000 sovs over the years keeping it going with repairs and servicing. That included an auto gearbox replaced by a garage. After that i cut costs by doing the work myself where I can. A lot of the faults were damage from taking it oft road for fun. Like oil seals failing. Yer won't get back the cost of previous repairs if yer sell it now. You will if yer keep it. The emotional tie is a big factor. You could look at rust proofing and other preventative measures to ensure it survives the future.
I wanted to keep my Freelander 1 as emotional tie's took over and I couldn't sell it. So I took it all apart and rebuilt it with newer parts from the Freelander 2 catalogue. So I still have my old adorable Freelander 1, but he now looks like a Freelander 2, with many more years of motoring ahead of us. Just like rebuilding an ole tratter but no welding was involved.
