Welcome to the forum buddy.. and may i say you made the right choice picking a ISF.
i did a lot of research b4 buying mine, had allsorts of debates against C63s RS4s and M3s.. but at the end just like you loving toyota, i been bought up by my dad who is a retired Toyota loving Mechanic.
also the guys on here were very helpful with their 1st hand experiences.
but apart from that, i wanted something that's not common, smoother than the competitors with Luxury and Power.. the ISF ticked all the boxes. ive had mine for 2 weeks and love it.. i know its still a new toy, and the excitement might ware off, but atleast i wont wake up one day dreading a common problem like the other German cars.
just make sure all the service is there when you get one.
apart from that i honestly cant knock the car. make sure you do post some pics when it arrives.
btw very nice Supra.
