I will chime in and offer my two cents since I currently own a 2007 F430 Spyder, have a 2021 Evora GT and have a Lotus Emira on order.
First, I will say the Ferrari F430 is a beautiful car and has an engine sound that can't be beat, especially if you have an aftermarket exhaust system installed. Even being a 15 year old car, the amount of people staring at the car is crazy for a car of this age as it looks incredible to this day. The lack of high-tech radios, touch screens, etc. is an attractive feature to me in an older car. A basic bluetooth radio with some decent speakers is all I need. Listening to the sound of the engine is incredible driving down the road as its very loud. Yes, the cost will be more than a Emira for a well maintained F430, but I also think the value will always hold in the Ferrari given the fact it's a Ferrari and everyone wants to eliminate the combustion engine! You can certainly perform a lot of your own normal maintenance if you are handy with cars.
With that said about the Ferrari, If I want to go cut up the back roads and get on it hard, I'm going straight to my Evora GT. The size of the car is perfect, the 6-speed manual is great, the seats are great, and I love the hand-built aspect of the car. A lot of car reviewers always dog this car of for its interiors, but personally I love the interior, even though it's a new car, it's still simplistic with analog instrument clusters, a basic double DIN radio and I honestly love the manual seats as you can get in and out in a split second. I do have the carbon pack on my car which I think makes a huge difference in the car's appearance. I love this car. For the price, I really don't think there is anything better if you want a great handling sports car that puts a smile on your face every time!
Finally, I just had an opportunity to drive the new Emira, and I'll be honest, I didn't walk away saying to myself that this is a car I want to own......or at least not yet! The FE version just felt boring to me. I thought the production seats sucked for a sports car, not overly impressed with the touchscreens, thought the dash over the instrument screen looked cheap and the engine noise sounded muffled and quiet to me compared to my Evora GT (I still have 3 cats on mine as well). The clutch was quicker to grab than the Evora and the shift throw was shorter as well. Supposedly, this was a Euro test car, and I was told the US car will have a slightly different sound.....a little louder. I'm hoping they will be offering some upgrades in the next year that will hopefully make this car more desirable to me as the body shape is beautiful but just not quite there yet with the upgrades that hopefully will be available sooner than later.
If I was debating between these three cars and had around $105K to spend (F430 in good shape will be at least 150K), I would go and buy an Evora GT in a heartbeat over the new Emira!
Good luck with your car buying decision!
