I drive a Hyundia i20 2011, it's small, compact, great on space, fuel economy and I love it. It's great on the motorways and in the city. The problem is the rust underneath.

I now need to start to look for another car and need something similar. Bhp would be the deciding factor for my next car. I need the same as what I have or above. I'm currently looking at the Kia Picanto, earliest model 2018-2022.

I'm finding all the info on the different models baffling - too many engine size choices. Can you suggest which ones to test drive and which one to avoid?

Also, I would like whichever car I buy to be undersealed due to the state my other car looks underneath. Do you have any advice on getting the car undersealed i.e. price, how long would I expect it to last and is it worth doing?
