I bought this car two years ago and it's been trouble-free since then. My previous convertibles were Miatas and VWs, and my wife didn't like to ride in any of those because of the road noise. The Miatas just were unsuitable for long trips. The Lexus is a true touring car - great handling, quiet interior, and enough space for luggage. The rather complex solid top goes up and down in … around 20 seconds and all you have to do is push a button on the dash. The interior is of high quality materials, although the leather seats were cracked and worn when the car came to me. I had them replace with new leather. Note that there are no after market leather seat covers available, so if you go the replacement route, it means custom hand-fitted work - not inexpensive.
My car has the optional 18 inch wheels, which probably improve handling, but the front and rear tires are different sizes, so rotation to even out wear isn't possible. The HVAC, NAV and radio screen is a touch screen and is very hard to read on a sunny day. Even harder if you wear polarized sunglasses. My screen was badly worn from the previous owner and Lexus does not offer a replacement - they want you to replace the entire radio for over $2K. I found a replacement screen on eBay for $125 and did the work myself. The result is as good as new. On a related note, updating the GPS maps can be done only by a Lexus dealer and the cost is over $300!
While my gas mileage has been good (24 mpg around town and 30+ on the highway), it does require premium gas. While I expected the three part roof to be a bit noisy and leak, it is perfectly quiet and as never leaked. On the highway, the car is quieter than my 2018 Lexus ES300H sedan.
If you're looking for a quality convertible, this would be a good choice provided you find one that's been taken care of and with low miles.
