Don't necessarily have a single one. Have a few different kinds of aesthetics / driving experiences I like -

For things I wouldn't mind owning some day:

• the early 1980s land cruiser SUVs, Ineos Grenadier is a modern equivalent; can function as a reasonable family car
• Ferrari 456 GT for a ~4 seater coupe
• tasteful japanese mods e.g. NA 1.8 Miata or a 70s Corolla fastback for something super fun to drive, the Miata might be the most fun car ever made
• Tuthill 911K for a classic hypercar
• Porsche 718 Spyder RS for a more advanced Miata
• Pagani Utopia for something to look at both inside and outside

For things I don't want to own but love that they exist:

• 911 GT3
• Murcielago SV, last big V12 with gated manual shifter
• Aventador SVJ just for the right bedroom poster
• Tourbillion
• the entire Koenigsegg lineup
