I've driven a few Legnums and Caldina ST215Ws ... Would definitely choose the Caldina. The manuals are great fun (not in the ST246W model shown in OP though). It's more fun and quicker overall than the Legnum. You can't do much with a Legnum to get better performance either due to lack of space. The Legnum also has filthy fuel consumption. Sorry to bag a Mitsi on a Mitsi forum :unsure: I was set on a Legnum until I heard about the fuel consumption from a few owners, then I drove a Caldina. Has a nice boy racer feel around the twisties and it's lighter and more economical. If you choose a Legnum, avoid the autos since they are not reliable.
You could also consider a Volvo V40 T4 ~1998 vintage (145kw or so). They go decently and if you do some reading you'll find that there are quite a few bolt on mods that can be done to them with minimal expense
They're only FWD though.
