If I didn't have the 4 seater and a family who occasionally want a ride out and wanted a bit of fun and to tinker and a ride around in for a year or so and not lose much money, I'd go for an early 2000's 4/4 with the 1.8 black top Zetec
A lowish Mileage one in great condition, all aluminium, galv chassis can be got for between £20-£27K
Williams have a super cute yellow one up for £25,995
You can buy a brand new whole engine on eBay for £700ish if anything goes wrong but all bits are pretty reliable and most other bits can still be bought through various suppliers and dealers
I'd take the windscreen off, put aero screens on - have a good three zip tonneau cover made and tootle around come rain or shine and enjoy
Then when bored, sell it on - cheap Morgan motoring
And miles and miles of smiles from everyone
