20, need help making a responsible bad decision.

Will keep it short and sweet. When I was 18 I purchased a 2006 Mazda Miata MX5. It cost $6,000, was a little beat up, but I enjoyed it quite a bit. I have since moved out on my own and come to terms with the fact I need something more practical, but I am still a sucker for a nice looking car. The AC on the Mazda is also completely shot and paired with a few cosmetic defects (paint peeling, interior issues) as well as 90+ degree days not being uncommon for the spring and summer season where I live, I believe I need a new car. Repairing the current one would likely cost close to its current value, and I am in need of a bigger car regardless. Sale value to a private party would likely be $4-5k, trade in value would be closer to $2,000.

Here is where the bad decision comes in:

I have my eyes set on a used Lexus RC 300/350, years 2016-2023. The ones I am looking at are used with 25 to 50 thousand miles on them. For simplicity’s sake, assume they cost an average of $27,000.

The good part is that these cars are mechanically bulletproof, parts are incredibly cheap, and serious issues are uncommon. They also tend to last upwards of 200,000 miles. Obviously I would get a Pre-purchase inspection done.

The bad part is that I am considered a high-risk driver and insurance is not going to love a 20 year old male behind the wheel of a sporty-ish coupe. I would also need to upgrade from liability to full coverage + gap insurance as my current car is owned and the Lexus would be leased. I also have a speeding ticket (no reckless driving) due to me driving like an asshole within the first three months of getting the Mazda. My current liability insurance on the Mazda is $283 per month. I have been shopping around and gotten quotes from other providers as low as $183.

Here is the part that makes me think this purchase is justifiable:

I currently have $200,000 in a money market fund I can withdraw any time, and $13,000 in a cash HYSA. My finances are as follows.

Expenses each month total $2,593. This accounts for rent, utilities, food, gasoline, car insurance, misc. I am considering a roommate when my lease expires this August which would cut my current rental expenses (rent plus utilities) from $1550 closer to $950ish.

Income each month is anywhere from a minimum of $4,150 to a maximum of $5,650. I hold a part time job that makes $1,000 a month, am given $200 a month from family, and make $600 a month in interest from the aforementioned assets. I also receive quarterly payments from a trusted source I am not allowed to disclose (take a wild guess). These payments fluctuate but for simplicity’s sake we can assume they are a minimum of $8,000 a quarter. However, it is not uncommon to see payments in the range of 17-23k. I will receive them until I am thirty.

Additionally, I would likely be able to secure a 4-5% interest rate for a 48 month term. Would love to hear input on any benefits a longer term might offer. If I sold or traded the Mazda it would cover the minimum $1,500 down payment. I would also not mind upping the down payment by a few thousand if I stood to benefit.

I am working (somewhat) hard to refrain from being a douche and believe that spending this life changing money frivolously is a bad idea, however I do think that I will only be young once and it would be nice to make a few calculated bad decisions now and again.

Is this an awful idea? or is it completely fine due to my assets and I’m just freaking out over my first ever large purchase.

Would appreciate any advice. Not going to answer scam/begging dms, so please do not bother. Thanks
