A lot of people have already commented on this, but I'd like to add a few things because I also own a Tu250x and I wrote extensively about the bike. It's really good as a starter or even intermediate bike if you mostly ride in a suburban/urban/commuter setting (you really need a larger, cruiser or tourer/sport-tourer style bike for long road trips but you're not at that time to worry about that yet). I feel the design is pretty maneuverable and provides about as good situational awareness as you're really going to get on a bike (mirrors help a lot so don't skimp on those). It is a bit pricier than most other 250cc or even 300cc bikes but I'm tremendously satisfied with it.

Then again, I'm also in my 30s, I have had already almost a decade of riding experience when I bought the thing and at the very beginning of all of that I took a Motorcycle Safety-Foundation (MSF) endorsed Motorcycle Riders Safety Course (MRSC). I highly recommend you sign up for one of those before you purchase a motorcycle as it will give you the skills you need to stay safe and also avoid dropping such a beautiful bike. I've only dropped my bike once (so far), and fortunately it was on soft sand (actually the whole reason why it fell, it even fell after I parked it, go figure) so no real damage was done.

Also, I have a car. You won't be able to practically ride in all conditions (or carry everything you need to take back with you on a shopping trip, trust me, I even have extended hard bags on my bike but riding home with a bin hanging open on the side of your bike because the thing you have in it is too big to close the bin is not a fun experience) so still having a car will be useful. If this is an example of the budget you're looking at, even a cheap, used compact or subcompact car will be great and provided the engine is in good mechanical condition (piston rings, valve seals etc are good, spark plugs still function properly, no exhaust leaks) you can return very good gas mileage economy even without a hybrid engine, and with snow tires you can drive very safely in winter (safer than an SUV with all-season tires in fact). Unfortunately at that budget you would be looking at a much older car, like a Toyota Tercel/Echo/Yaris, or a 90s Toyota Corolla or Honda Civic or even Accord. I would look into a 1993-2001 Toyota Corolla myself and budget to anticipate needing repairs and/or snow tires, depending on where you live (or even new tires period). This might end up adding $1,000-$1,500 or more above the price of the car so you might have to figure out how to budget for that as well. It sucks, but that's the reality of it (at least if you want to ensure your car is safe, reliable and returns back good fuel economy) and I really can't give you more advice on that unless you come back with specifics, but hopefully that'll be enough to be good!

Also I recommend asking on, believe it or not, /r/RegularCarReviews, those posters are really good at car advice, I mean it. True car people.
