You'd be surprised...
GT86 is a 3 year finance deal - can't get any longer directly from Toyota it seems - so it's final 'bloom' payment value is relatively high.
Clio would be 4 years - so the final bloom payment is far far less than the GT86.
So the monthly payments are within £15 of each other...
Don't do it you traitor! Get a 200 then we can go racing!
