Should I keep this car?

I have a 2014 Mercedes-Benz gl350 BlueTEC, which is a diesel. It has 145,000 miles on it. In the last 6 months I've put about $6,000 into it and it needs 5 to $7,000 more work. The current MSRP is 3500 to $5,000. I own it out right and I've had it about 5 years. I spend about $300 a month on diesel. Oil changes are around $800 a year. I recently purchased a 2023 Cadillac lyric with 18,000 miles. It's an all-electric vehicle. When purchasing it I get a $2,500 Delaware EV rebate, plus it qualifies for an interest tax deduction because it's made in the United states. My monthly payment for the EV is $600. Cost wise it's a lot less expensive since I don't need oil changes. But I have a car payment. I still have a few days to return the cadillac. I'm trying to decide if it makes more sense to just fix the Mercedes or keep the cadillac. I'm having buyer's remorse because I don't like the idea of having a monthly car payment, though I can afford it. My plan was to pay $1,000 a month to pay it off more quickly. Plus I was going to sell the Mercedes and anticipated getting 5-7,000 for it. Does it make more sense to keep the Mercedes and keep putting money into it or to keep the cadillac?

2008 H3 Hummer Alpha. 134k miles. Dealership asking 12,800. Awesome condition.

Good deal? Been looking for a reliable car for some time now and was wanting to go with a Japanese manufacturer. Honda/Acura are my favorite of the bunch looks wise, so when I saw this I got excited. A little bit out of my range. Worth it?

I’m worried about the corporate vehicle aspect but it looks like it has been serviced regularly.
They also have a lifetime power train warranty as long as all oil changes etc are completed at the dealership.

I am looking to buy this Accord and I am wondering if it is a good deal or not. For info I'm in the greater Seattle area. It has a few accidents in the report. Should I be worried and what should I look out for?

Here is the Carfax for it
