I went from a fantastic 363bhp Evo 5 to a not so fantastic 75bhp Fiesta 1.25 zetec!
I hated every minute of it but wanted to sell the Evo to put a bigger deposit down on a house we were buying. The only thing i did enjoy was the cheaper insurance & my weekly petrol bill being halved!
Don't think you can compare a Fiesta to a 100hp. The 100hp has way more character and is so much more fun to drive. Congrats on selling the Chelsea tractor HPsaucey and welcome to the forum. I'm sure you'll love the Panda as well as the reduction in running costs!
