Basically I bought my ford KA a few months ago back in March time.it's around 11 years old and it cost me just over £1400. Recently I bought new tyres and my friend did a relatively short health check on it as it's due for MOT at the end of July. He told me I'd need a new lower arm, and a new power steering grid thingy as mines cracked? He also said that I'd need my gearbox fixing as it's leaking and new whiper blades(which isn't all too expensive) I've already had my rear lights fixed and as I said previously I bought new tyres. As he's my friend he said he'd be able to give me a relatively good deal on fixing the rest however it still would cost me a fair amount but I thought I could handle it.
However, yesterday my bonnet started smoking and a warning light came on out of the blue everything was fine up until that point. After a few hours of me being distraught and crying I managed to get the car home. My friend looked at it and my heater matrix is destroyed? & apparently it's a large job and quite costly. I'm a student currently on a poorly payed job, having a gap year and hoping to work full time. I feel as though I'm spending money I don't have on a car that people keep telling me isn't worth it. But it's like my baby & it's so difficult to even comprehend getting rid of.
I just want some type of advice, being an 18 year old female who knows nothing about cars is really and truly difficult. I don't know what's best? Any advice would be much appreciated
