It's not too bad actually - I'll have had it three years this coming April and I think I've only spent about £400 on maintanence. insurance is £350 a year. Ok, so it only gets 20mpg around town but as I only drive it a few times a week I only spend about £25 a week in fuel (my Lexus LS400 with a 4ltr V8 is only slightly worse on fuel). Also, as it's a pre-2001 car it's just flat rate road tax of £205 a year.
To me, a boring car is one that can ONLY be viewed as an efficient means of transport - one that doesn't give you goosebumps, one that doesn't have any nice toys, one that isn't exciting to drive, one that is "too common", one that you could never think about "lets go for a drive" in.
Take my Westfield as an example - as a means of 4 wheel vehicular transport it's almost entirely and utterly inappropriate - it has no boot, no windscreen, no roof, no heaters - however it's undoubtedly the best car I've ever driven - you don't go anywhere in it - you just go out in it for the sheer enjoyment of "driving".
My attitude towards cars are actually very similar to why I'm now into ebikes - I like the technology, I like building stuff, I like tinkering. Saving money/the planet is of no concern to be as far as my ebike goes. Just as I like driving fast cars, I also like being on a bike - an ebike means I'll be on a bike more often as fitness is now an issue that I'm getting older. My ebike balances my car fleet perfectly - it means I can keep the mileage and maintenance down on them whilst getting some exercise
