All boils down to budget and how well you can restore a car ..
without restoration it all comes down to budget .. you can pick up mintyish mk2 Granadas for under 2k... 3k being a really goody Allthough they are getting rare now as most have been banger raced .
Zodies... lots of money for good ones
Same as Escorts .. 4 drs are even creeping up in price as mint Mk2's are now fetching big money (anyone got one they dont want????) so like i said ... whats the budget ... and go with 2k on insurance , if it cheaper then you can buy whatever car you get some toys
