Advice on buying 2004

been lurking for a while and this is my first post.

1) I want a car for mostly highway driving. I’m a soccer mom about maintenance (I don’t like), but I like how Prius has a large knowledge base for repairs and problems. Otherwise, my needs are basic as it gets.

Here’s the listing for what I’m looking at:

2004 Toyota Prius Hybrid NEWER HYBRID BATTERY 165k Miles - $3,995​

​

I’m willing to pay so much for a 15 yo car bc Tampa Hybrids has an impeccable reputation around here and does a lot of service.

The owner told me his rate for battery replacement is $2400 or $1800 for his rebuilt batteries. Also $2k for ABS actuator.

So humor me and assume the dealer is legit (I’ve talked to a couple ppl in person who recommended and his reviews online are impeccable):

What should I ask/look for when I go look at it?

My budget is about 6k (I like to pay cash), and I figure this would allow me 2k for surprises/repairs.

My main concern is that there’s nothing about the service history. I will ask but wanted to ask here first...
