The perigee is easiest; with an eccentricity of 0.5, the periastron is 15,000,000km. Half the semimajor axis.
With an eccentricity of 0.7, the periastron is 9,000,000 km.
Summer in the 0.5 case would be short and hot, with violent weather especially just after the periastron. Winters would be cold, especially after apastron.
Summer would be very extreme in the 0.7 case, but short; winter would be long and cold. I think you'd need weather machines in this case, just to make the planet even slightly habitable.
I haven't worked out how long each quarter would last yet.
