I'm thinking 150mph+ and/or sub 5 seconds 0-60 time is "high performance", so I guess the most common around my neighbourhood would be various BMW Mx, plus a few fast Mercs, but I'm lousy at identifying them as I find them kinda boring. Annoyingly never seen an SLS AMG though.
Lots of Imprezas of various generations, far less Evos.
In terms of true Supercars, I see GTRs relatively frequently, at least a couple a month, next up is the R8, then various Ferraris, usually 360s, 430s or Californias. Gallardos I see rarely, Murcis even more so, and I haven't seen an Aventador or Huracan in the wild. Surprisingly not seen a 458 or 12C either
GTs, there are quite a lot of Astons around, mostly DB9s and DBS, but V12s and other models are more scarce. Never seen an original Vanquish. Also plenty of Bentley Contis around here.
TVRs are surprisingly, well, not common, but not rare either. Usually Cerberas or Griffiths, occasional Tuscan, Tamora or 350C. Only seen one Sagaris though.
Elises are pretty common, but Exiges much less so. Occasionally spot an Esprit.
Last weekend during one drive I saw two GTRs, an R8 and a 430, but that was unusual.
