I think you'll find the word "repayments" in my post had you read it. I've not skipped over the fact it is a loan. Loans are a legitimate way of getting something sooner at an increase in cost. OP could save every month for the next six years and not have what they want, or they could have it now at a cost of around an extra £1,300 spread over the same time period, i.e. about £20 extra per month for the privilege of having use of the car for all those extra years. Saying "loans... lol" is not some magic way of discrediting an argument. The question whether the loan was high risk or couldn't be afforded. But it's clearly within the OP's budget and is also to purchase a sale-able asset which further offsets risk. They're buying second hand so there shouldn't be some massive and rapid depreciation.
Honestly, "lol" is not really a very good method of debate when I went into some actual detail on yours and showed the problems with what you wrote. I.e. that your post is wholly supposition based on you not perceiving value the same way as the OP.
Nothing flimsy about them. Care to actually engage and try to refute them, or is your response going to just be "lol" and "you're arguments are flimsy"? Because those are the responses of someone who can't actually put their finger easily on a reason why the other person is wrong. Oh, and of course calling the other person "desperate". That's a popular tactic YouTube level argument as well.
