I currently have a 66 plate Mazda 6. It’s starting to get a few errors pop up with regularity so I’m in the market, I have a young ish family - 2 kids.
I get a company car allowance - around £500 a month pre tax.

I’m I best off buying a 2nd hand electric outright, if so, any recommendations for 15-18k (ish).

Should I do Tesla pcp (I’ve genuinely no idea what pcp is) and get a model 3 personally?
I’m waiting to see what the company car list looks like also, but any suggestions as to what’s best?

Any cars to avoid, any cars to look at?
